Maybe a bit OT, but otherwise close to gentoo as well (as we all configure our kernels individually ....) (see ps below):
When I configure my gentoo-server for Linux KVM, how to get the clock-issues right, in terms of correctness and performance? I assume that I am not the only one scratching his head ... but maybe some of us simply hesitate to ask ;-) HPET, RTC, TSC, blah ... A new server with a Xeon-CPU tells me: "kvm: SMP vm created on host with unstable TSC; guest TSC will not be reliable" Ah, ok. Is that bad? Could I do something? Should I? My question is // questions are: Are there any recommended kernel-config-settings for a performant and non-drifting KVM-server? Is there a "best practise"? What is your experience, your recommendation? Maybe it should find its way into the gentoo wiki :-) Thanks in advance, Stefan ps: yeah, I know, this should go to the linux-kvm-ml in an ideal world. We all know that we would end up subscribed to dozens of mailing-lists just to get our jobs done .... so pls be tolerant in terms of "what is off-topic". thx.
